组合注解(RequestMapping的变形)
- @GetMapping = @RequestMapping(method = RequestMethod.GET)
- @PostMapping = @RequestMapping(method = RequestMethod.POST)
- @PutMapping = @RequestMapping(method = RequestMethod.PUT)
- @DeleteMapping = @RequestMapping(method = RequestMethod.DELETE
1、原始springMVC的请求
package com.example.springdemo.hello; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import org.springframework.web.bind.annotation.ResponseBody; @Controller public class OrginController { /** * 原始的写法 * @return */ @RequestMapping(value = "/orginController",method = RequestMethod.GET) @ResponseBody public String orginController(){ return "orginController"; } } 如图：
2、使用SpringBoot的请求
package com.example.springdemo.hello; import org.springframework.web.bind.annotation.*; import java.util.HashMap; import java.util.Map; @RestController public class RequestDemoController { /** * RestController相当于Controller+repsoneBody */ /** * 通过@PathVariable接收参数 */ @GetMapping(value="/test1/{id}/{name}") public Map<String, Object> getMap(@PathVariable("id") String id,@PathVariable("name") String name) { Map<String,Object> map = new HashMap<String, Object>(); map.put("id",id); map.put("name",name); return map; } /** * get请求的用法 * @param id * @param name * @return */ @RequestMapping(value = "/gettest1",method = RequestMethod.GET) public Map<String,Object> getController(@RequestParam(value="id") String id,@RequestParam(value="name") String name){ Map<String,Object> map = new HashMap<String, Object>(); map.put("id",id); map.put("name",name); return map; } @GetMapping(value="gettest2") public Map<String, Object> getController2(@RequestParam(value="id") String id,@RequestParam(value="name") String name) { Map<String,Object> map = new HashMap<String, Object>(); map.put("id",id); map.put("name",name); return map; } /** * post请求的用法 */ @RequestMapping(value = "/posttest1",method = RequestMethod.POST) public Map<String,Object> postController(@RequestBody User user){ Map<String,Object> map = new HashMap<String, Object>(); map.put("id",user.getId()); map.put("name",user.getName()); return map; } @PostMapping(value="posttest2") public Map<String, Object> postController2(@RequestBody User user) { Map<String,Object> map = new HashMap<String, Object>(); map.put("id",user.getId()); map.put("name",user.getName()); return map; } /** * put请求的用法 */ @RequestMapping(value = "/puttest1",method = RequestMethod.PUT) public Map<String,Object> putController(@RequestBody User user){ Map<String,Object> map = new HashMap<String, Object>(); map.put("id",user.getId()); map.put("name",user.getName()); return map; } @PutMapping(value="puttest2") public Map<String, Object> putController2(@RequestBody User user) { Map<String,Object> map = new HashMap<String, Object>(); map.put("id",user.getId()); map.put("name",user.getName()); return map; } /** * delete请求的用法 */ @RequestMapping(value = "/deletetest1",method = RequestMethod.DELETE) public Map<String,Object> deleteController(@RequestParam(value="id") String id){ Map<String,Object> map = new HashMap<String, Object>(); map.put("id",id); return map; } @DeleteMapping(value="deletetest2") public Map<String, Object> deleteController2(@RequestParam(value="id") String id) { Map<String,Object> map = new HashMap<String, Object>(); map.put("id",id); return map; } }通过POSTMAN测试接口的截图
1）path
2）get请求
3）post请求
4）put请求
5）delete请求
